Agoseris glauca

Crepis accuminata
Lomatium grayii
Phlox longifolia
Native Perennial Legumes
• Astragalus utahensis
• Lupinus polyphyllus
Temperature, Photoperiod, Mycorrhizal inoculum,
Length of Chill to stimulate regrowth, Nitrogen
fixing symbionts.
Agoseris glauca
Few collections, Small in size
Low density populations, Low
growing make it more difficult
to detect.
Seed Limited
CPP studies
Increase plots for more seed
Astragalus utahensis
Astragalus utahensis
• Germination – Cold Stratification complete.
• Acid scarification methodology – complete.
• 1 CG planted – plants grew slowly, poor root
development, held over summer – lots of
mortality.
• Additional plants growing for spring planting
• Cultural practices increase plot growing –
harvest methods.

Tragopogon dubius
• Common Gardens at Nephi,
Wells, Orovada – last did not bolt.
• Germination work – Total viability
and rate by date.
• Biomass – 2 sites
• % field ripe seed by date
• Flower head production

Stipa comata
• 2 CG Nephi, UT,
Wells, NV
• Germination work
• Methods to break
dormancy without
breeding it out.
• Additional CG Spring

Phlox longifolia
• 1 CG planted.
Container growth
poor – root mass.
• Transplant timing
critical to annual
growth
• CPP studies
• Additional CG 2005
